Ice is one of the most abundant materials in our Universe and important for a wide range of environmental processes and scientific disciplines. In this talk, I will present an overview of recent progress in ice research from our lab at UCL. Firstly, the detection and characterisation of stacking disorder in the ‘ordinary’ ice I will be discussed as well as the possible occurrence of stacking disordered ice in the Solar system and the effect stacking disorder has on the shape of snowflakes.[1] Using cryogenic ball milling of ice I we recently discovered medium-density amorphous ice.[2] Is this new amorphous form of ice the glass of liquid water? To test the suitability of salt hydrates for energy storage in heat batteries we recently built the HeatMaster instrument which can test up to six samples in parallel.[3] Using the HeatMaster, we found two new nucleating agents for the popular sodium acetate trihydrate phase-change material. To study ice nucleation in supercooled water droplets we built another instrument called the IceBox. Using aluminium surfaces, it was found that the chemical compositions of aluminium alloys, their surface roughness and age impact on their ice nucleation properties. Finally, mixtures of low-density amorphous ice and hydrophobic hydrocarbons were prepared as the exist in comets.[4,5] The effects of the hydrocarbons on the crystallisation temperature and desorption properties were investigated, and the structure of water in the first hydration shell of adamantane was solved with neutron diffraction.
